Someday in the future, we may look back on the technology we're using today and laugh that we were using electrons to carry data in and around computers.

Intel Corporation this week announced a research prototype representing the world's first silicon-based optical data connection with integrated lasers. The link can move data over longer distances and many times faster than today's copper technology; up to 50 gigabits of data per second. This is the equivalent of an entire HD movie being transmitted each second.

The transmitter chip is composed of four such lasers, whose light beams each travel into an optical modulator that encodes data onto them at 12.5Gbps. The four beams are then combined and output to a single optical fiber for a total data rate of 50Gbps. At the other end of the link, the receiver chip separates the four optical beams and directs them into photo detectors, which convert data back into electrical signals.

While telecommunications and other applications already use lasers to transmit information, current technologies are too expensive and bulky to be used for PC applications.

Today computer components are connected to each other using copper cables or traces on circuit boards. Due to the signal degradation that comes with using metals such as copper to transmit data, these cables have a limited maximum length. This limits the design of computers, forcing processors, memory and other components to be placed just inches from each other.

Think you know tech? If you don't have a handle on every single one of these 15 tech facts, habits, and efficiency tricks, you're not living up to your potential.

1. Don't double-click everything. Windows 101: Double-clicking is how you open items in Windows. It's not how you open links in your Web browser, click buttons in dialog boxes, or do pretty much anything else--and if you reflexively double-click, you might accidentally zip right past something important or submit a form twice. If you don't need this reminder yourself, chances are you know someone who does.

2. Use slashes and backslashes in the appropriate situations. Let's get it straight: / is a slash (or forward slash, if you must), and \ is a backslash. Backslashes are conventionally used for Windows file paths (C:\Program Files\Whatever), while slashes are used for Internet addresses (http://www.pcworld.com/howto.html).

3. Record the exact error message. When your PC crashes, it'll usually try to tell you why it is doing so--albeit with a string of numbers and letters that you won't understand. Write the message down in its entirety (or take a screenshot, if possible) so you can later plug it into Google or give it to your tech support agent. If your PC didn't provide an error message, go to Action Center (in the Control Panel) and see if it shows up under 'View archived messages' or 'View problems to report'.

4. Bring deleted files back from the dead. When you delete a file from your PC or memory card, you're not wiping it off the actual hard drive. Instead, you're simply removing the index information that tells your PC where the file is, at which point the PC is free to treat the part of your disk that contain that file as empty space that it can write something else to. If you've accidentally deleted something, undelete utilities such as Recuva can help you find those files again as long as you haven't already written over that file with something new.

While I am writing this post I have my other computer being reformatted because of so malware attack!

1. My Avast free antivirus keeps on popping up saying that i has deleted some virus.2. Malwarebytes (antimalware) is not opening. I've downloaded new version but no joy.3. My Display Monitor is flickering... and I guess it has something to do with my windows driver or faulty connection line/ports.4. It is getting slower and slower.

Here is what my computer do.1. Download torrent :)2. Play downloaded movie or music.3. Do my work if I my second computer is not available.

Guess the top 2 of my Computer activity started this issue, though I am not really sure about it.

If Malwarebytes is working I am pretty sure this will not happen to me.

Are you an Smartphone and Tablet user? Be happy! Qualcomm to ship fastest chips for phone.

Qualcomm will start shipping its fastest Snapdragon dual-core chip for smartphones and tablets in the fourth quarter, with devices possibly launching by the end of this year, the company said on Monday.

The company will ship the dual-core QSD8672 chip with CPU cores running at up to 1.5GHz, said Mark Frankel, vice president of product management for Qualcomm CDMA Technologies. The chip could go into smartphones, tablets and low-cost laptops, he said.

Frankel pegged the launch date for devices with the new chip for early next year, adding that aggressive vendors could launch products "by Christmas" -- or the fourth quarter -- this year, Frankel said.

The chip is a follow-up to the dual-core MSM8660 Snapdragon chip, which started shipping in the second quarter. The 8672 has a faster processor than 8660, which includes CPU cores running at 1.2GHz. The processor in the 8672 chip is based on an Arm design and will be manufactured using the 45-nanometer process.

The chip is similar to the 8660 design with a raft of improvements compared to its previous single-core chips, Frankel said. That should bring better power management and performance to devices, Frankel said.

One thing I like with Windows 7 is its fast processing time compared to its predecessors Windows Vista and Windows XP. Yeah! I'm pressure you'll agree with me that it also faster than XP. But the good news this operating system can get even faster with simple tricks.

Learn how Windows 7 get faster.

1) Uninstall bloatware that came with your laptop or PC. Or even apps you installed but no longer want. Head to Control Panel | Programs | Uninstall a program and take the hatchet to anything, such as unwanted games or software, that you'll never need. Many programs will load processes at boot time and take up valuable RAM and CPU cycles. While you're in here, you can also click Turn Windows Features On or Off and scan the list to see if there's anything you don't use. You might also want to try out software utilities such as PCDecrapifier and Revo Uninstaller.

2) Limit start-up processes. In the Start button's search box, type MSCONFIG, then head to the Startup tab. You'll likely see a slew of apps, mostly for system support, but you'll be able to identify some that clearly aren't necessary. There's absolutely no need to have Google Update or even QuickTime running all the time, for example. Don't delete those that support your hardware or security, but anything blatantly nonproductive can go. You may have to check the program names online with a site like processlibrary.com to see what they are—they may even be malware. If you want to get more granular, run Microsoft's Autoruns utility.

3) Add more RAM. Windows 7 isn't as much of a hog as Vista, but if you're moving from XP, the memory requirements are greater.

4) Turn off search indexing. If you do a lot of searching, this won't appeal to you, as some searches will be slower. To turn off indexing, open the Indexing Options Control Panel window (if you just type "index" in the Start button search box, you'll see that choice at the top of the start menu), click Modify and remove locations being indexed and file types, too. If you want to leave search indexing on, but find that it occasionally slows you down, you can stop its process when you need extra speed. Right-click on Computer either in the Start menu or on the desktop, and choose Manage. Then double-click Services and Applications, then Services. Find Windows Search, and double-click on that. From this properties dialog, you can choose a Startup type of Manual or Disabled to have the process silent by default.

5) Defragment your hard drive. Your disk stores data in chunks wherever there's disk space, regardless of whether the space is contiguous for one file. Defragging tidies everything up and blocks a program's bits together so that the reader heads don't have to shuttle back and forth to read a whole executable or data file. Windows 7 comes with a built-in defragger that runs automatically at scheduled intervals, but if yours is set by default to run at a time when your PC is usually turned off, it won't get defragged. You can either change the scheduled time, or defrag on demand. Just type "defrag" in the Windows Start Menu search bar, and click on Disk Defragmenter. The version of the utility is improved in Windows 7, and shows more information about what's happening on your disk than Vista did.
